Question

我正在尝试安装一个django-cms变种（wagtail）并让一切正常，直到我在做'./manage.py syncdb'。那时我得到如下追溯：

Traceback (most recent call last):
  File "./manage.py", line 10, in <module>
    execute_from_command_line(sys.argv)
  File "/opt/software/virt_env/virt1/lib/python2.6/site-packages/django/core/management/__init__.py", line 399, in execute_from_command_line

  File "/opt/software/virt_env/virt1/src/wagtail/wagtail/wagtailsearch/indexed.py", line 43
    indexed_fields = {field: dict(type="string") for field in indexed_fields}
                                                   ^
SyntaxError: invalid syntax

似乎for循环语法还可以......任何想法？或者python 2.6.6和python27之间的语法有很大的变化吗？

我在RHEL 6.4（2.6.32-358.el6.x86_64）上运行PYTHON 2.6.6和DJANGO 1.6.1，postgres 8.4.18

非常感谢任何想法或想法

Answer 1

dictionary comprehensions were added in Python 2.7。你正在运行2.6。所以你需要改变这一行：

indexed_fields = {field: dict(type="string") for field in indexed_fields}

进入这个：

indexed_fields = dict((field, dict(type="string")) for field in indexed_fields)

SyntaxError：在django上运行syncdb时语法无效
